This textbook provides the foundation for a course on physiology and hygiene. In studying the body, it is very desirable that the scholar should, as far as possible, see and handle the parts described. Children especially can learn much more readily in this way than from any description. A dissection of a cat or dog or rabbit, illustrating the lessons, will make the text clear, and fix the essential facts in the mind. Or, if this can not be done, pieces of muscle and of cartilage, joints and bones, a heart, the lungs, a liver, an eye, and other organs, can be obtained from the butcher, to serve the same purpose. The apparatus mentioned in illustration of the action of organs--the bellows, the syringe, and others that may occur to the teacher--should be shown. Models and plates are also valuable. A few clear ideas of the structure and functions of the body will be worth much more to the children than many details imperfectly understood. On the subject of stimulants and narcotics, the author has endeavored to make no statements which are not susceptible of positive proof, and to present only facts which children are capable of appreciating. Much more might be said which does not come within the province of such a work as this. A glossary is included.
